Abstract (en)

[origin: WO2011042342A1] The invention describes a novel method for deaerating liquids by adding 0.0001 to 5.0 % by weight, preferably 0.0002 - 1.0% by weight, especially preferred 0.001-0.2% by weight of branched polyether-polysiloxane copolymers to said liquids. Only those branched polyether-polysiloxane copolymers are used in which the polyether radicals are SiC-bonded via hydrocarbon radicals to linear siloxane chains and said siloxane chains are connected to each other via SiC-bonded organic radicals, preferably divalent to decavalent, preferably divalent to tetravalent, hydrocarbon radicals, which may contain one or more heteroatoms selected from the group consisting of oxygen and nitrogen atoms.
